Step-by-step explanation:
-x - 3 = x + 3
Solving like terms
-3 - 3 = x + x
-6 = 2x
-6 / 2 = x
-3 = x
1) yes
2) x=-4,y=-7
3) x= -3, y=4
4) x= -1, y=2
5) x= -5, y=-8

Answer:
The slope of line is 0 given points (2,8)(7,8)
Step-by-step explanation:
We need to find slope of line given points (2,8),(7,8)
The formula used to find slope of line is: 
We are given:

Finding slope using formula:

So, the slope of line is 0
Since a rhomubs is a 4 sided quadrilateral when parallel lines intersect within we solve for the triangles that are the result of the intersecting lines m<2=10, m<3=10
